Titan Yellow CAS 1829-00-1

Report 1.
Take 44.3 grams of metatitanic acid (TiO2 content: 38.7%), 0.91 grams of chromium trioxide, and 1.74 grams of antimony trioxide, place them in a 300 mL beaker, add 120 mL of deionized water and defeat for half an hour, filter to acquire a combination, and mix the blend The main product of Titan Yellow of Ti0.9 Cr0.05 Sb0.05 O2 was acquired by toasting directly in a muffle heater at 900 ° C for 3 hours. Transfer the key titanium yellow product to a grinder and grind for 20 mins, and after that move it to an air powder meter for air movement grinding for 30 minutes to acquire a titanium yellow product with a fragment size of 8 microns.

Report 2.
Take the hydrolyzate moisturized titanium dioxide prepared by the sulfuric acid titanium dioxide manufacturing process. The sedimentation rate is 150mm/20min. Wash the hydrated titanium dioxide with faucet water at 60-65 ° C. The iron material (determined as Fe) in the once-washed wastewater is 95mg/L; Include the hydrated titanium dioxide gotten by washing once with faucet water to make a slurry with a focus of 325g/L and a temperature level of 60-65 ° C. Add sulfuric acid (computed as H2SO4) to 49g/L and trivalent titanium (computed as Ti2O3) to 0.5 g/L., after 2 hours of therapy, add orthotitanic acid sol calcined seeds (computed as TiO2) based on the mass portion of the TiO2 material in the slurry to be treated, the addition ratio is 5%; use 55-60 ° C desalted water to deal with the acid The dealt with hydrated titanium dioxide is cleaned with water. The iron web content (determined as Fe2O3) in the second water washing wastewater is 8mg/L; the hydrated titanium dioxide acquired by the second water cleaning is included in desalted water to make a slurry with a concentration of 330g/L; use hydroxide Potassium changes the pH value of the slurry to 2.5 ~ 4.0; based upon the mass portion of the TiO2 contained in the slurry to be treated, the enhancement proportion of antimony oxide (determined as Sb2O3) is 11%; the addition ratio of nickel oxide (determined as NiO) The proportion is 6%; the enhancement proportion of zinc oxide, zinc sulfate or zinc chloride (determined as ZnO) is 0.5%; after adding the above reagents, mix for 0.5 to 1 hour, press the slurry to dry the water and calcine, and the maximum calcining temperature is regulated at 1000 ° C, the rutile crystal material in the calcined item is 99.5%; squash the calcined product with a mechanical pulverizer to a fineness of 0.05% to acquire a high near-infrared reflectance titanium yellow key product; desalinize the Titan Yellow key item Water is utilized to make slurry, and the slurry is ground with a sand mill. Zirconium silicate grains of 1.2 to 1.4 μm are used. The ground slurry is cleaned with desalted water. The conductivity of the cleaned wastewater is 75 μm/ cm. The slurry is Press completely dry the wetness; completely dry the product to get rid of the moisture, add trimethylolethane in an amount of 0.2% of the mass of the smashed material, and get a high near-infrared reflectance titanium yellow product through vapor flow squashing.
